Cycling has just been allowed again on the prom, partly due to campaigning, partly because it's often wider than the road next to it and also to form part of NCN2 which may be completed in the 23rd Century. Invalid Carriages are known to go along there at a fair old lick but as the sight lines are so good and the prom has become shared use, the chance of conflict is reduced (particularly if you are the pedestrian/cyclist and the scooter driver has cataracts
I made a comment recently as Chair of the local Cycle Forum about how the 'CARNAGE!' and 'MAYHEM!' that the local papers were praying for when cycling was readmitted failed to materialise. I was criticised by a local editor who wrote that anything I said would be 'too subjective'. I wrote back stating that if the local papers wanted to be really objective then they should consider the following; In the last 15 years, 4 pedestrians were seriously injured by cyclists whilst over the same time frame 19 people were killed and 201 seriously injured by motorists.
My point is that Invalid Carriages are also probably at the lower end of the accident stakes and yet the 'Elephant in the room' is totally ignored. Certainly there needs to be more education on both sides but I just think that picking on the elderly and partially abled is a pretty desperate and cheap shot at increasing overall safety.
